SE AL FOR METAL BINDERS.

Application filed November 1, 1926, Serial No. 145,626, and in France December 8, 1925.

Employment of a metal binder of the type which is passed around the mouth or throat of a bag or sack and then sealed at its ends ensures considerable labour saving wherever materials have to be packed in bags 01' sacks, and general adoption thereof is to be expected by all industries and trades dealing with materials of that nature, such as lime, cement, fertilizers, flour, coal, etc.

Hitherto, however, adoption of the said binder has been limited owing to the fact that there existed no seal specially designed for use therewith, so that, consequently, recourse had to be had to common seals for string ties which render the binder, and thus the package provided therewith, only partially proof against unauthorized tampering.

The object of my invention is to overcome this defect, and for this purpose, I apply the tubular rivet in an entirely new manner tothe sealing of metal binders of the type above referred to.

I have illustrated, as an example, an embodiment of a device contrived according to my invention in and by a drawing appended hereto and wherein:

Figure 1 is an elevation of the rivet proper, of which Figure 2 is a top plan view.

Figure 3 is a View partly in section and partly in elevation showing the said rivet in combination with a binding wire and a label.

Figure 4 is a top plan view of Figure 3, the latter being supposed to represent the whole rivet.

My new seal is composed of a tubular rivet consisting of a metal body A, of cylindrical or other shape, one end of which is provided" with a collar 3 of substantial width and on which any useful marks may be engraved, while its other end 0 is adapted unauthorized tampering with the latter as for outside crimping over the hoops on the two ends of the binder wire D (Figure 3), 45 such crimping being effected. by means of special pincers.

Such crimping unites very tightly the two hoops of the binder, thereby preventing any was possible with any seals used hitherto.

My seal is therefore a positive completion of the metal binder. Like this binder it means simplicity and saving as well as ready and prompt putting on. Besides being tampering-proof, it permits paper or other tags or labels E to be afiixed in a proper manner calculated to prevent them from getting detached as they areliable to with any of the methods necessitated by the use of other seals.

Having now particularly ascertained and described the nature of my said invention as well as the manner in which the same is to be performed, I declare that what I claim is:

A sealfor bags or sacks, comprising a wire adapted to be passed around the throat of the bag or sack and to have'its two end portions twisted tightly together to choke 0 said throat and thereby close it completely, said wire having av terminal hoop on each said end portion, such hoops adapted to be brought into registration with each other; and a rivet having a tubular body portion adapted to be inserted through the two registering' hoops and provided at its inner end .with. a collar of substantial width to engage the inner hoop, the outer end of the tubular body adapt-ed to be crimped outwardly so tightly over and entirely around the outer hoop so as to unite the two hoops securely together.

In testimony whereof I afiix my signature,

JEAN MALLARONI
